Witnesses: Innen tor,

delivery end of vintermittently turned shown in Fig. 3, and these traysorcrates are placed one after another on the rails b/ next to the feeddoor y' over the tank a..

To return empty trays or crates from the delivery end to the receivingend of the apparatus, track rails g and guides h ai'e provided above thehood or cover, as shown in Figs. 1, 3 and, 4, the ends of these returnrails and guides being preferably inclined downwardly as shown inFig. 1. The track rails are provided at intervals with rollers p tofacilitate the movement of the bottle trays or crates thereon.

To automatically feed the loaded trays or crates into the apparatus, totransfer them from one carrier to the next, and to discharge them fromthelast carrier at the proper times, a reciprocating feed bar g passeslengthwise through the a paratus b'e-` tween, parallel with and alittllej below the track rails g. This bar is provided at intervals withlpivoted dogs r, which foldfor swing from an upright position toward thethe apparatus, and are held normally in an upright position againsttheir lateral tail pieces r by springs s. At the delivery end of themachine the bar g is bent downwardly and provided at its lower end withroller guides t, which run on a horizontal guide rail u parallel withsaid bar, as shown in detail in Fig. 9. For intermittently moving thebar g back and forth..the distance required to carry the bottleotrays orcrates into the apparatus, transferv them from one carrier to another,and finally discharge them at the delivery end of the apparatus, alinkbelt v provided with a tooth w, is mounted on sprocket wheels parallelwith said bar,which is provided with lugs y and 2 in the path of thetooth w.

The rotary bottle carriers are intermittently turned a distancecorresponding with the distance between adjacent rows of racks, by amutilated gear 2, which meshes with a pinion 3 on the shaft n,and thelink belt v is the distance of one complete circuit While the rotarycarriers are at rest by a similar mutilated gear 4, which meshes with apinion 5 on a shaft connected by bevel gears 6 and 7, as shown in Figs.2,

.3, and/with the shaft of one of the sprocket wheelsiiie The gears 2 and4 are fixed on a shaft parallel with the shaft n and provided with aworm gear 8 meshing wit;l a worm 9 on a transverse shaft which isVpi'ifvided with a pulley 10, as shown in Figs. 3v and 5. As shown inFigs. 2, 3, 5, 6, 7 and 8, each of the piiiions and 5 is associated witha shoe 11, having a fixed relation thereto and adapted after eachcomplete revolution to engage with the periphery of a flange 12 on thedriving gear and to prevent the pinion from V'turning when it is notengaged by the teeth of the driving gear. The toothed portions of thetwo driving gears 2 and 4 are so arranged thatl while one pinion isbeing turned, the other is held stationary.

The pulley 1() on the worin shaft may be driven iiom an)T convenientsource of power. As shown in Figs. 3 and 5, it is belted to a pulley 13on a shaft 14, extending across the delivery end of the apparatus, and)rovided with a driving pulley 1.5 and a chitc i 16, operated by a lever17, for starting and stopping the mechanism.

A`water supply pi )e 18, provided with a valve 19, is connected with theseveral tanks a, and c at the bottom by branches which are provided withvalves 20. A drain pipe 21 provided with a valve 22, as shown in iig. 1,connects with one of the branches in such a way that either the tanks aand c or the tank b can be drained when the valve 19 is closed, byopening t'he proper valves 2() and the valve 22.

The tank c is provided with an overflow pipe 23, which prevents thewater from rising above the desired level in any of the tanks, the tanksa and c being connected with each other as hereinafter explained, andthe middle tank b having an overflow connection 24 into the tank a., asshown in Figs. 2, 4, and 7,

Each of the tanks a and c is partially divided by a central verticalpartition 25, arallel with the axis of the rotary bottle carriers, intotwo subdivisions, in which the water may be maintained at differentteinperatures. The subdivisions on the descending side of the carriersare connected by circulating ipes 26 and 27. The pipe 26 opens direct yinto the bottom of the tank a, but hasan extension 28 leading upwardlyinto the tank c and terminating therein above the lower edge of thepartition 25. The pi ie 27 opens at its ends into the ii per parts ofsaid tanks. A constant circu ation of water through the subdivisions ofthe tanks a. and c with which the pipes 26 and 27 directlycommunicate,is maintained while the apparatus is in operation, by a small propellerwheel 29 in the ipe 27. This wheel may be driven from t ie main shaft 14by connections substantially as shown in Figs. 2, 3, and 8. By thismeans substantially the saine temperature is maintained in thesesubdivisions of the tanks a and c. The middle tank I is provided asshown in Figs. 1, 2, 7 and 8, with steam pipes or coils 30, for heatingthe water therein, and the water is agitated so as to keep it atapproximately the same temperature throughout the tank by a pro iellerwheel 31, which may be connected with and driven from the main shaft 14,as shown in Figs. 2 and 8.

To prevent the ivotally suspended racks from swin ing, an to hold theirtrack rails g in line wit i the stationary track rails g, verticallymovable shoes or plates 32 are connected with the hood or cover, asshown in Figs. 1, 4 and 5, and are pressed downwardly by springs 33against the horizontal facesvon The tooth fw passing back on the underside the up er sides of the yokes f at one or both of the belt v,engao'es with the lug a and ends o said racks as they are broughtv intoline with the doors y' and j.

-A perforated pipe 34 is arranged acrossv the upper part of the tank cin position to direct a spray or stream of Water against the bottles onthe ascending side of the carrier in said tank, asA indicated in Fig. 8and is connected by a pipe 35 with a branch of the supply )ipe 18, saidpipe 35 being provided witli a valve 36.

The greater portion of thetanks a, b and c may be located below theoperating floor, which is indicated in F igs. 1, 3 and 4 by the lines37. j

In the operation of the apparatus the water in the middle tank orcompartment b is heated to and maintained at a pasteurizing temperatureof about 140 F. by the steam pipes or coils 30. The water inthe'subdivisions of the tanks or com artments a and c on the descendingside o the carriers (indicated by arrows) is maintained at about4 110F., whilel the .water in the remaining subdivision of thetank a rismaintained at about 140 F., and the Water in the remaining subdivisionof the tank c is maintained at about 88 F. Although thev temperatures inthe different parts of the apparatus may be varied somewhat withoutmaterially affecting the results attained, those above stated have beenfound in practice suitable for the purpose. The driving mechanism beingset 1n motion, the rotary carriers are intermittently turned together inVthe direction indicated by arrows, bringing` one row of racks afteranother into line with the doors and j. The bottles containing thebeverage to be asteurized are taken from the filling mac 'ne and placedlin trays or crates o on the stationary track rails g next to thereceiving tank a, the first tray or crate being placed so that the dog rat the adjacent end of the feed bar g will standy u i behind. it, asindicated in Fig. 1, when said bar is in its normal position. While therotary carriers stand at rest with a row of racks in line with the doorsand j', the feed bar g is advanced b the engagement of the tooth w onthe lin belt v with the lug y on feed bar q, said belt being drivenintermittently by the `mutilated gear 4 hereinbefore described, so thatthe tooth w makes a complete circuit at each movement, starting fromabout the point where it is shown in Fig. 1, clearing said lug` ly atthe limit of the advance movement of said bar and leavin the lug z, asshown in Fig. 0, in the path o the return movement of said tooth on theunder side of the belt. By this advance movement of the bar g, the firsttray or crate is carried into the uppermost rack of the carrier the tanka, opening vthe door j, which closes behind it.

moves the bar g back to its original position,

lthe dog 7' at its opposite endvbeing turned back against the tension ofits spring s so as to pass under the tray or crate just deposited in theadjacent carrier. Trays or crates filled with` bottles are placed oneafter another in position to be fed into the apparatus, as .he foregoingoperations are repeated. After making 'a complete circuit through thereceiving and warming tank a, each tray or crate of bottles which hasbeen gradually raised to or approximately to a pasteurizing temperature,is transferred automatically by the feed bar q into the second carrier,wherein it makes a complete circuit through the pasteurizing tank b andis held for a certain eriod at the pasteurizing temperature. rom thiscarrier each tray or crate of bottles is transferred in like manner bythe action of the feed bar q into the last carrier, wherein it makes acomplete circuit through the tank c, its temperature beinggraduallylowered till it isy in proper condition for delivery from the apparatus.From the last carrier each tray or crate of bottles is discharged uponthe stationary track rails g, opening the door y" which closes behind itat that end of the ap aratus. Here the bottles are removed from t etrays or crates, and may be conveniently assed directly to a labelingmachine, t ereby avoiding, as in the feeding of the pasteurizingapparatus directly from the bottling inac lne, unnecessary handling. Theempty trays or crates are returned to the feeding operator upon theelevated track rails g. As the trays or crates are transferred from onecarrier to another, and discharged from the last carrier, their lacesare taken by other trays or crates, w ich are fed into the apparatus,advanced from one carrier to the next, and finally discharged from thelast carrier by the action of the feed bar g and its dogs r during everystop of the carriers. If 'crates or trays of freshly filled bottles aresupplied by the feeding operator so that a tray or crate will be fedinto the apparatus every time the carriers stop,` the apparatus will bekept filled, and a tray or crate will be delivered from tho apparatus ateach stop of the carriers. As the heated bottles received into the lastcarrier from the pasteurizing tank b descend in the tank c, they aregradually cooled, imparting` their heat to the water in that subdivisionof the tank. Water thus heated and tending-to lrise, is forced by the.propeller 29 through the pipe 27 into the upper part of lthecorresponding subdivision m tank a, where it is utilized to graduallywarm the cool bottles and their contents as they descend in that tank.The water being thus cooled and tending to descend in this subdivision4of the apparatus, is conveyed back through the pipe 26 and itsextension 28 into the corresponding subdivision of tank c, where it agamserves to cool the bottles and their contents as they descend therein.

By extending the return pipe 26 upward in the tank c above the loweredge of the partition 25 on the side next to that with which the pipe 27is connected, the water in the subdivision on the opposite side of saidpartition is kept cooler. As the bottles ascend in tank c, they aresubjected to sprays or jets of fresh cool Water from the ipe 34, the suply of such walter being regu ated by the va ve 36, so that the bottlesand4 their contents as they are delivered from the apparatus, will havethe desired temperature.

The apparatus as herein shown and described may be used to advantage forsoaking,

cleansing and sterilizing bottles or the like and sterilizing thecontents of bottles, or

the like, as Well as for pasteurizing. Various modifications in thedetails of construction and arrangementof parts of the apparatus may bemade without materially affecting its Y mode of operation and withoutdeparting from the principle and scope of the/invention.
